Relational Operators in C Programming
Introduction to Relational Operators
Relational operators in C programming are used to compare two values or variables. These operators help in decision-making by returning true (1) or false (0).
Relational operators are widely used in conditions, loops, and logical expressions.
List of Relational Operators
Common Relational Operators
==Equal to!=Not equal to>Greater than<Less than>=Greater than or equal to<=Less than or equal to
Example of Relational Operators
int main() {
int a = 10, b = 5;
printf(“a == b: %d\n”, a == b);
printf(“a != b: %d\n”, a != b);
printf(“a > b: %d\n”, a > b);
printf(“a < b: %d\n”, a < b);
printf(“a >= b: %d\n”, a >= b);
printf(“a <= b: %d\n”, a <= b);
return 0;
}
Output Explanation
Each comparison returns:
1if the condition is true0if the condition is false
This output is useful in conditional statements like if and loops.
Using Relational Operators in Conditions
int main() {
int age = 18;
if(age >= 18) {
printf(“Eligible to vote”);
}
return 0;
}
Relational operators help in controlling program flow.
